Arcane Devourers are bizzare creatures and fabrications of uncontrolled energies near the Sanctum of the Moon.[1]

Attracted to the Well of Eternity, the first of these beings appeared early in history. Elves were able to destroy them, but still, one by one, arcane devourers have found gateways into the world. Their origins are unknown, though some suspect that they are agents of the Burning Legion. [2]
